Cannot import/reference class from external package

I have two packages mg.networktest and mg.networktest.server, both need access to the same class for registering/serializing classes that need to be send over the network. I think the best practice would be to create it on the server package and include it in the client.

However i cannot get the class referenced properly. I also tried adding another package but that is not allowed I think. But it just does not recognize my other package. The imports below all get The import mg.networktest.server cannot be resolved. I can get it to import mg.networktest.*; but that just references itself.

import mg.networktest.server; //This is the exact package
import mg.networktest.server.Network; //This is the physical class/.java name
import mg.networktest.server.Network.ChatMessage; //This is one of the classes inside the .java that needs to be included.

To be more clear:

Package 1: (mg.networktest.server) has a Network.java with class ChatMessage.
Package 2: (mg.networktest) needs the class ChatMessage from package 1.
Package 2: (mg.networktest) cannot do: import mg.network.server.*;.
How do i get access in package 2 (mg.networktest) to class ChatMessage from package 1 (mg.networktest.server)?

Solution

If your import statement causes a compilation error, verify the following:

You've used the correct syntax. For a single type name, use the syntax import TypeName;. To import type names on demand from a package or class scope, use the syntax import PackageOrTypeName.*;.
You've named a package and/or class that currently exists. Check the path, and check the spelling.
If the imported class is in a different Eclipse project or library, verify that it's on the build path for the importing class's project.
Rebuild the projects containing the importing and imported classes. Usually this isn't necessary if you have Build automatically enabled.
